How Cloud Computing Works
To explain how Cloud Computing works we’re going to use an analogy – the development of electrical utilities.
In the early days you couldn’t buy electricity from a supplier. Factory owners had to build their own power station and generate electricity themselves. That required a lot of additional upfront capital and increased the fixed operating costs of the factory. But there was no alternative.
Sound familiar? It was just like buying your own servers and applications and then installing them in your own “data centre” in your office.
Let’s move on to the next stage. Some bright spark thought of building a huge power station and selling the electricity to a number of factories.
The benefits were:
At the end of the month they got a bill for the amount of electricity they consumed. It was simpler and more flexible. Because it was so much easier soon everything was powered by electricity.
Using Cloud Computing
Cloud Computing is similar to the development of the electricity grid. Instead of building and running your own mini data centre in your office you just buy computing power as you need it, just like electricity.
Instead of having network cables connecting your workstations and printers to the servers in the corner of your office, imagine the cables stretching across the internet to data centres where the servers, applications and data are now located. That’s how Cloud Computing works!
This means you can access your applications and data, anywhere you can get internet access.
You can use any device – office PC, home PC, laptop on the move, iPad, Mac, mobile phone, home PC, etc.
To the user it looks the same and works the same, but it’s much more efficient for you the business owner.
